Wild Alaskan Salmon
The omega-3 fats found in wild Alaskan salmon help fight inflammation throughout your body, including in your brain, and offer numerous protections to your brain cells. For example, a study found that older women with the highest levels of omega-3 fats had better preservation of their brain as they aged than those with the lowest levels.
In another research, when boys were given an omega-3 supplement, there were significant increases in the activation of the dorsolateral prefrontal cortex part of the brain. This is an area of your brain that is linked with working memory.
They also noticed changes in other parts of the brain, including the occipital cortex – the visual processing center and the cerebellar cortex which plays a role in motor control. You can get omega-3 fats in therapeutic doses by taking a supplement, but if you’re looking for a food source, wild Alaskan salmon (among with anchovies and sardines) is among the best.
